| abstract | 1517557 Polysiloxane elastomers having organic linkages RHONE POULENC INDUSTRIES 30 Sept 1975 [1 Oct 1974 11 Feb 1975] 40055/75 Heading C3T A thermoplastic polysiloxane elastomer contains units of the formula wherein each R<0> is a C2-10 alkylene or cycloalkylene radical optionally bearing 1-4 Cl or F atoms; each # is a direct bond or -SiR2-, -SiR2O-, -SiR2-(CH2)1-3- or -SiR2- C6H4- (R being Me or Ph); each R<1> is an alkyl, haloalkyl, cyanoalkyl, aryl or haloaryl radical, each R<2> is a C1-4 alkylene or alkylidene radical; each X is -O-, -S- or -NR<4>- or -CO-O-, -CO-S- -CS-O- or -OS-S- attached to R<2> via O or S (R<4> being H or C1-6 alkyl); each # has 1-30 C atoms and is (i) an optionally chlorinated alkylene, alkylidene, cycloalkylene or arylene radical or a a mono- or poly-cyclic divalent saturated, unsaturated or aromatic heterocyclic radial, or two or more such radicals linked directly or via -O-, -S-, -NR<4>-, -COO-, -CONR<4>-, O -SO2-, -N=N-, -N=N-, -CO- or -PO(R<5>)- (R<5> being C1-4 alkyl, cyclohexyl or phenyl) or (ii) a benzenetriyl, naphthalenetriyl, pyridinetriyl or =C6H3-E-C6H4- radical (E being C1-4 alkylene or alkylidene, -O-, -S-, -COO-, -SO2-, -CO- or -CONH-) in which one valency is attached to X and the other two to T below when T is each # is -O-CO-0-, -NR<4>-CO-NR<4>-, -NR<4>-CO-O, -O-CO-CO-O-, -SCO-CO-S-, -NR<4>-CO-CO-NR<4>, -T-R<11>-T-, wherein R<11>, R<111> and R<1111> are di-, tri- and tetra-valent organic radicals and each T is -CO-O-, -CO-S-, -CO-NR<4>-, -NH-CO-NR<4>-, -NH-CO-O- or -NH-CO-S- attached at either end to a divalent group #, or is attached via the -CO- groups to trivalent #; and n is 1-2000. They are prepared by reaction of the silanes in which each R is a C2-10 ethylenically unsaturated organic radical, with the siloxanes H-SiR<1>2-(OSiR<1>2)n-H. In examples silanes having two groups CH2=CH-SiMe2-CH2O- linked by the sequences (Examples 1 and 2 and 8-11), (Examples 3 and 4), (Example 5), (Example 6) and (Example 7), are added in place of a Pt catalyst to siloxanes HMe2Si(OSiMe2)nH, where n is 14 to 37, in toluene, cyclohexane, dioxan or butyl acetate. The products, in the same solvents or chloroform, are cast into films, or moulded into sheets. The unsaturated silanes are the subject of copending Specification 1,517,558. |
